The “Mid-and-Long-Term Decommissioning Action Plan 2024” released by TEPCO on March 28, 2024, does not indicate specific details on the dismantling scenario and timeframe of the PCV/RPV/buildings.

Although investigations have been conducted on the processing of the wastes such as rubbles removed for further expansion of fuel debris retrieval and secondary waste generated from contaminated water treatment, no investigations, including estimates, have been conducted on waste generated during dismantling of PCV/RPV/buildings.

Since rubbles, etc. generated in large quantities was contaminated by fallout, while previous waste storage and management practices have incorporated classification using surface dose rate as an indicator. It is planned to understand radioactivity concentration to recycle of the waste inside the facilities in the future.

Efforts are being made to address the waste hierarchy, which consists of the priorities of (1) waste generation reduction, (2) waste volume minimization, (3) reuse, (4) recycling, and (5) disposal, as practiced in other countries.
